Design

During his visit to Beijing in 2013, Daan Roosegaarde, Dutch artist, designer, and innovator, discovered the air quality in the city was so poor that children were kept indoors and he was unable to see out the window of his hotel room.

But Roosegaarde saw more in the smog than most; he saw the possibility for clean air for the people of Beijing. He returned to his team of designers at Studio Roosegaarde and they set to work on designing, building, and testing (what they claim is) the world’s largest air purifier.

Standing at almost 23 feet high, the Smog Free Tower can clean 30,000 cubic meters of air per hour using the same amount of electricity as a home water boiler (about 1,400 watts). According to Roosegaarde, the system can collect, capture, and turn to dust about 75% of dangerous PM2.5 and PM10 airborne smog particulates, creating a bubble of clean air in its midst.

Studio Roosegaarde turned to Kickstarter to get the project going and were able to build their first Smog Free Tower in Rotterdam in September of 2015. One year later, with the support of the Chinese Ministry of Environmental Protection, the Smog Free Tower opened in Beijing’s 751 D.Park on the first stop of its global tour.

The smog particulates collected from the tower’s Beijing stay have been used to create 300 limited edition Smog Free Rings, each crafted by a member of Roosegaarde’s design team. The purchase of the rings aids in the development of the project and its global tour.
